Re: Transferring collections built on a Mac to an Intel machine

In the past I've got around this problem by converting the big-endian
database to text on the big-endian machine then converting the resulting
text file to a little-endian database on the little-endian machine (or
vice-versa).

So, if you built the collection on the Mac you'd do something like the
following to convert the gdbm database to text:

db2txt album.bdb > album.txt

Then, after copying the collection to the Intel machine (including
album.txt) you'd do something like:

txt2db < album.txt > album.ldb

You should then have both a .ldb and a .bdb gdbm file and the collection
will work with either byte-ordering.

Stefan.
